Investigation of failure of crane rope from DSV DSND PELICAN

This report describes the inspection of a 34LR whipline rope on the DSV PELICAN which failed in service on 17th March 2001 whilst deploying a subsea module. The whipline was rated at 10 tonnes. The weight of the module (weight in air 3.5 tonnes) was such that even allowing for dynamic loading and the effect of added mass, the integrity of the rope must have been severely impaired for failure to occur.
